BURNER.

Application filed June 17, 1918. Serial No. 240,284.

A To all whom it may concern:

Be it known that I, CHARLES D. MORGAN, a citizen of the United States,residing in the city of Albany, county of Albany, and State of New York,have invented a new and useful Improvement in Burners, of which thefollowing is a specification. The object of "myinvention is to effect asaving in the amount of gas consumed in operatin a gas range for cookingpurposes and particularly of the amount of gas necessary to maintainboiling point after the same has been reached. My improvement canmaintain a cooking or boiling process with an expenditure of aboutone-third of the gas consumed by the forms of burners tested byapplicant now in use. I am aware that various burners have been coveredby Letters Patent for the purpose of conserving fuel but none of theseattain the results of my improvementwhich shows a saving of as greaterthan the most efiicient of these improved burners.

The means by which I secure the efliciency of my burner is by aconstruction which brings the burner used in contact with the bottom ofthe vessel to which the heat is being applied. It has been recognized.in this art that the closer the burner could be brought to the vessel tobe heated and to the plane of the grid or framework of the stove themore efficient the results would be. This has not been made possiblewith the form of burners used because it was believed that to get aperfect combustion secondary air supply was necessary and thiscombustion was not obtainable when the vessel and burner were contiguousto each other. Various methods have been invented and patented to secureperfect combustion through supplies of secondary air and to allow forcloser contact between vessel and burner. My form of burner operateswithout any special allowance for secondary air and may be placed in thesame plane as the grid and may touch the vessel to be heated and obtainsa perfect combustion. The flame follows the vessel and does not floatfrom under the vessel and because the burner impinges on the vessel themaximum efficiency is secured from the gas used. There is no attempt tosupply secondary air by the construction used and the smaller than themouth itself or the by the reference letter burner mounted thereon.

Similar letters refer to similar parts of the different figures shown.

The mixing tube A is made in elbow form wlth the burner mouth B. Theedges of this month are projected inwardly in the form of an annular lipas at C so as to leave an annular opening in the mouth slightly ed es ofthe mouth may be bevelled and pro ected within the mouth as is shown inFig. 2. The burner top D is of annular shape and is mounted on the boltE which screws into the boss F in the mixing chamber A. The art D may beconstructed with bevelled e ges as shown in Fig. 2. In Figure 2 the caphas been designated by the reference R, the mouth of the mixing chamberby the reference letter S, the mixin chamber proper and thestem or boltsupportin the burner cap "by the reference letter The supply of gas issent into the mixing chamber by the cock G and 7 openings for air toenter the mixing chamber are provided atthe points H' the means ofcontrolling the admission of air being those in general use and wellknown in the art. The burner is secured in the gas range positioned withreference to the grid as is shown in Figs. 1 and 3. The part D being inthe same plane as the supporting irons I.

The gas on entering the mixing chamber A is mixed with the air whichgets access to the chamber at H and then moves through the mixingchamber to the mouth of the burner where it strikes the part D which isscrewed into the boss F so as to leave a space between its'lower surfaceandthe edges vof the burner mouth B and the mixture trolled by raisingand lowering the part D.-

The part D and mouth B when made with bevelled edges as shown in Fig. 2permit the flame to be turned down to a low point by the cock G withoutbeing blown out by possible draughts. I

V I have described preferred forms and do not consider my inventionlimited thereby as these forms may be materially changed withoutdeparting from the spirit of my invention. I

What I claim is:

1. A burner for a gas range consisting of an air mixing chambercomprisin a tube shaped in elbow form with gas an air connections andcontrols at point of connection, and an outlet port having bevellededges and having a lip constructed on the lower edges substantially asdescribed; a burner head comprising a solid flat disc mounted above theoutlet port and having its edges bevelled so as to make the lowersurface of lesser diameter than the upper surface; a

bolt adjustably mounted in base of mix- 2. The combination in a gasrange of a mixing chamber with a mouth, an adjustable solid disk mountedabove the mouth with a flat top surface adapted to impinge on the bottomof the vessel to be heated, and the grid of the as range, the said gridand the said adjusta le disk being mounted in the same plane.

In witness whereof I have signed this specification in the presence oftwo witnesses the 12th day of June, 1918.
